  • Methods and systems for attenuation correction in medical imaging
    Patent number: 7813783
    Abstract: Methods and systems for imaging a patient are provided. The method includes scanning a patient and acquiring a plurality of frames of cine computed tomography (CT) images during one complete respiratory cycle. In one embodiment, a method is provided that includes selecting an organ of interest in the cine CT data and selecting a value for each pixel in the organ of interest that represents the maximum density measurement. An attenuation corrected positron emission tomography (PET) image is constructed based on the maximization of the pixel intensity of the organ of interest in the CT attenuation correction map. Incorrect attenuation correction values for PET images can be avoided by utilizing the CT attenuation correction map.

  • Device-less gating of physiological movement for improved image detection
    Patent number: 7574249
    Abstract: A method of imaging an object using a medical imaging system is provided. The imaging method acquires a stream of sinogram data. Changes in the stream of sinogram data corresponding to movement of the object are detected. The method selects portions of the stream of sinogram data. An image of the object based on the selected portions of the sinogram data is generated.
